Geoscience is a regulated profession in Ontario and most of Canada. Just as engineers, doctors, lawyers, and many other professions are regulated in Canada, so are geoscientists. Practising geoscience without a licence can result in legal action and financial penalties as defined by the Professional Geoscientists Act (2000). PGO is the regulator of geoscientists in Ontario and as such, governs the practice of geoscience in this province. PGO registers geoscientists and confers the Professional Geoscientists (P.Geo.) designation on them. It also handles complaints and discipline with respect to the actions of P.Geo.’s. Over 2000 P.Geo.’s are registered with PGO.

Aspiring to be a Professional Geoscientist?

If you wish to be qualified to practice geoscience in Ontario and elsewhere in Canada, start early! Become a student member of PGO. Get advice from PGO staff on which courses are necessary to meet PGO’s knowledge requirements. Enjoy the benefits of networking with Professional Geoscientists, the PGO Mentoring Program, and staying up-to-date with the geoscience field and related industries by subscribing to our weekly e-newsletter, Field Notes.

  5. Get four years of geoscience work experience that meets PGO’s requirement.
  6. Apply for change of designation from GIT to P.Geo.

Student Outreach 

PGO has started its annual outreach to Ontario universities with in-person information session on P.Geo. registration. The outreach will continue through to January 2024. PGO acknowledges our Councillors who volunteer their time to deliver this information session in partnership with Registration staff, Eilidh Lewis, P.Geo., Registrar and Gabrielle Hosein, P.Geo., Assistant Registrar. We also acknowledge the faculty and staff from Ontario universities for working with us to make this outreach possible.

Join PGO’s Mentoring Program

The purpose of PGO’s Mentoring Program is to provide a forum for experienced professional geoscientists to share their knowledge, insight and experience with student members, Geoscientists-in-Training (GITs) and newly minted P.Geo.’s. It was developed to provide professional development and growth opportunities for both the mentors and the mentees. The Mentoring Program is a mentor-and-mentee driven program. PGO’s role is to help facilitate the connection of mentors and mentees.

The length of the mentoring relationship is determined by the participants. Find out more about the Mentoring Program by clicking on this page.
